Which bird of the family "Phylloscopidae" is in the picture?

The wood warbler ("Phylloscopus sibilatrix") is a common and widespread leaf warbler which breeds throughout northern and temperate Europe, and just into the extreme west of Asian Russia in the southern Ural Mountains.

This warbler is strongly migratory and the entire population winters in tropical Africa.

The wood warbler is 11–12.5 cm long, and a typical leaf warbler in appearance, green above and white below with a lemon-yellow breast. It can be distinguished from similar species, like the chiffchaff "P. collybita" and the willow warbler, "P. trochilus" by its yellow supercilium, throat and upper breast, pale tertial edges, longer primary projection, and by its shorter but broader tail.

Various factors associated with forest structure, including slope, forest cover, proportion of broad-leaf forest, canopy height and forest edge length, all influence the occupancy rates of this declining forest species. Conservation measures are therefore required that provide and maintain the wood warblers preferred forest structure. There is also a preference for forest in the non-breeding season; however, this habitat is declining in wintering areas such as Ghana.
